Penetration Testing for Manufacturing

Manufacturing organisations increasingly face cyber threats as industrial environments become more connected through Industry 4.0 initiatives, IoT sensors, and IT/OT convergence. Manufacturers are targeted by ransomware groups seeking to disrupt production, nation-state actors pursuing intellectual property theft, and supply chain attackers looking to compromise products or processes.

Penetration testing for manufacturing must address both corporate IT systems and operational technology including PLCs, SCADA systems, industrial robots, and manufacturing execution systems (MES). Testing must account for the safety implications of OT system compromises and the operational impact of production downtime.

The automotive manufacturing sector has specific requirements through TISAX, while manufacturers in the EU defence supply chain must address CMMC requirements. NIS 2 extends cybersecurity requirements to many manufacturing subsectors. Regular penetration testing helps manufacturers protect intellectual property, ensure production continuity, maintain supply chain trust, and comply with industry-specific regulations.

Manufacturing Pen Testing FAQs

How do we pen test without disrupting production?+

Testing should be carefully scoped and scheduled. Passive techniques can be used on production systems. Active testing may be performed during maintenance windows or on test environments that mirror production.

Should we test our smart factory IoT devices?+

Yes. IoT devices in manufacturing environments are common attack vectors. Testing should cover device firmware, communications protocols, cloud backends, and integration with production systems.

What manufacturing-specific risks do pen testers find?+

Common findings include flat networks connecting IT and OT, default credentials on industrial equipment, unpatched PLCs, insecure remote access, and weak segmentation between production lines.
